The Surry Power Station, operated by the Virginia Electric and Power Company, is located on a peninsula that extends into the James River on its south shore. The tip of the peninsula is known as Hog Point, and it is approximately 30 miles (48 km) upstream from Chesapeake Bay and 50 miles (80 km) downstream from Richmond (Fig. 1). The section of the river bordering this peninsula is the transition zone between fresh water and saline water, where the salinities encountered are near the tolerance minima for most estuarine and marine species and near the tolerance maxima for freshwater species. Therefore, the biological community consists of a few resident species that can tolerate the entire range of conditions, and of visitors from upstream that can survive until their tolerance limits are exceeded. The region is biologically significant mainly as a nursery ground and migration corridor for fish species that are harvested elsewhere. The fish populations inthe vicinity of the power station have been monitored by VEPCO personnel. VIMS was engaged by VEPCO to monitor the lower trophic levels, including the phytoplankton, zooplankton, benthic macroinvertebrates and fouling organisms. The monitoring study has been in progress since May, 1969, and intensified sampling programs for phytoplankton and zooplankton were conducted in the years 1975 through 1977. The present report covers the study period January through December 1977.
